摘要

目的：超声剪切波弹性成像（SWE）测量大鱼际肌肉弹性可能有助于腕管综合征（CTS）的诊断和评估，但关于CTS患者大鱼际肌肉SWE的信息缺乏。本研究的目的是研究CTS患者大鱼际肌肉的弹性。方法：22例转诊诊断为CTS的成年患者（27只手）和20名健康志愿者作为对照（20只优势手）。用SWE测量了静息和捏捏两种情况下大鱼际肌肉的弹性模量。比较各组各肌肉在两种条件下的弹性模量及百分比变化。结果：静息时，患者组拇短外展肌弹性模量低于对照组(20.6±5.6 kPa vs. 25.0±8.5 kPa；P = 0.034)。而弹性模量(87.9±49.0 kPa vs. 62.5±28.5 kPa；P = 0.044)和百分比变化(373.3±336.4% vs. 169.2±116.0%；p = 0.006)，患者组APB高于夹紧对照组。对于对手拇趾和拇内收肌，两组间弹性模量无显著差异。结论：CTS患者APB的SWE存在差异。未来的研究需要进一步探讨SWE在诊断CTS和评估预后方面的准确性。

Elasticity Characteristics of Thenar Muscles in Carpal Tunnel Syndrome

Objective

Measurement of thenar muscle elasticity by ultrasound shear wave elastography (SWE) may be useful for the diagnosis and evaluation of carpal tunnel syndrome (CTS), but there is a paucity of information on SWE of the thenar muscles in patients with CTS. The purpose of this study was to investigate the elasticity of the thenar muscles in patients with CTS.

Methods

Twenty-two adult patients with a referral diagnosis of CTS (27 hands) and 20 healthy volunteers as a control (20 dominant hands) participated in this study. The elastic modulus of the thenar muscles was measured with SWE in two conditions, rest and pinch. The elastic modulus and percent change between the two conditions for each muscle were compared between groups.

Results

The elastic modulus of the abductor pollicis brevis (APB) in the patient group was lower than that in the control group at rest (20.6 ± 5.6 kPa vs. 25.0 ± 8.5 kPa; p = 0.034). However, the elastic modulus (87.9 ± 49.0 kPa vs. 62.5 ± 28.5 kPa; p = 0.044) and percent change (373.3 ± 336.4% vs. 169.2 ± 116.0%; p = 0.006) of the APB in the patient group were higher than those in the control group with pinch. For the opponens pollicis and adductor pollicis, there was no significant difference in the elastic modulus between groups.

Conclusion

Patients with CTS showed differences in SWE of the APB. Future studies need to investigate the accuracy of SWE in diagnosing CTS and assessing prognosis.

期刊介绍： Ultrasound in Medicine and Biology is the official journal of the World Federation for Ultrasound in Medicine and Biology. The journal publishes original contributions that demonstrate a novel application of an existing ultrasound technology in clinical diagnostic, interventional and therapeutic applications, new and improved clinical techniques, the physics, engineering and technology of ultrasound in medicine and biology, and the interactions between ultrasound and biological systems, including bioeffects. Papers that simply utilize standard diagnostic ultrasound as a measuring tool will be considered out of scope. Extended critical reviews of subjects of contemporary interest in the field are also published, in addition to occasional editorial articles, clinical and technical notes, book reviews, letters to the editor and a calendar of forthcoming meetings. It is the aim of the journal fully to meet the information and publication requirements of the clinicians, scientists, engineers and other professionals who constitute the biomedical ultrasonic community.
